Adding java.property.com.ibm.as400.access.AS400.fallbackCCSID=<CCSID> in the adapter tra file.
Note:
1). CCSID represents "Coded Character Set Identifier" which is a 16-bit number that represents a specific encoding of a specific code page. For the mapping between CCSID and the code page, refer to the IBM Globalization website at the following link:
http://www-01.ibm.com/software/globalization/ccsid/ccsid_registered.html
2). In order to make sure that the Unicode characters can be processed properly, "TIBCO Messaging Encoding" must be set as "UTF-8" in TIBCO Designer. For more information, refer to the TIBCO Designer document under "User's Guide -> Chapter 2 Managing Projects and Resources : Saving Projects".
3). Redeploying the application is required if the property is added into adas400.tra which is located in <TIBCO_HOME>/adapter/adas400/<Version>/bin.
